changing pool water

[Watermom]

Yeah, I know. Probably even 2 or 3 times before. (More likely 2000 or 3000 times before!!

How you don't algae and scaling with those numbers is kind of a miracle.
CH 1000?
CYA 300?
TA 240?
FC 3?
TC 5 ?
(therefore CC=2)

Your FC needs to be AT A MINIMUM 8ppm and you need to shock the pool to 25ppm just to get rid of the CC.

You also need to go through the TA lowering procedure--with your CH at 1000, I suggest you follow Chem_Geek's and Waterbear's usual advice about getting TA down to around 50.

Draining and refilling will help get those out-of-control #s back in control, but not if you are going to continue to use tabs. Right now, the ONLY forms of chlorine you should be using are bleach/Liquid Chlorine. Lithium Chloride would be OK but it's insanely expensive.

Good luck!

Change water??? I've had the water in my 20x40 IG pool for 14 years, and yes believe it or not it is still wet!
